Specification of Letters Patent. I

Patented Aug. 19, 1919.

Application filed October 2, 1917. Serial No. 194,332.

To all whom it may concern:

Be it known that I, AJNTON MAE, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Pliers, of which the following is a specification.

This invention relates to pliers and it is the principal object of the invention to providel pliers having the jaws thereof so arranged as to'mov'e in planes parallel to each other at all times, thus permitting an article arranged therebetween to be firmly and positively engaged by the same.

Among other aims and objects of the invention may be recited, the provision of a device of the character mentioned with a view to compactness, and in which the number of parts are few, the constructlon sun- .ple, the cost of production small, and efficiency and operation high.

- The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding of the same.

In the drawings Figure 1 is a side elevation of the improved pliers; V

Fig. 2 is a vertical transverse section therethrough Fig. 3 is a detail in perspective of one of the jaws of the same; and

Fig. 4; is a fragmentary detail in perspective showing the jaw engaging arms of the crossed handles.

Having more particular reference to the drawings and in connection with which like reference characters will refer to corresponding parts, 1 and 2 represent the crossed handles of the plier construction, the same being bifurcated and pivotally connected as at 3. The bifurcations provide arms 4: upon the ends of said; handles, the said arms being offset intermediate of their ends as at 5, as

formed in the outer ends of the arms 4 and serve as means for permitting pivotal engagement of the aws of the pliers, hereinafter referred to. Located within the bifurcations forme by the arms 4: are jaws 7 and 8, the same being provided with rigid guide arms 9 integral therewith and extended substantially at right angles from these guards, the guide arms 9 being receivable in guide openings or slots 10 formed in the opposite jaws trans versely thereof. Obviously, by providing the guide arms 9 and the openings 10, movement of the jaws 7 and 8 to and from each other will be such as to maintain the same in planes parallel to each other at all times. Therefore, an article arranged between the jaws will be firmly and positively gripped thereby. If desired, the engaging portions of the said jaws 7 and 8 may be serrated as at 11. Transv'ersely disposed openings are formed in the jaws 7 and 8 and receive pivot pins 12 therethrough, which pivot pins have the opposite extremities of the same arranged in the bearing openings 6 formed in the outer ends of the arms 4. By so engaging the arms 4: with the aws 7 and 8, the same may be moved to and from each other by moving the crossed handles 1 and 2 in the desired direction.

Manifestly, the construction shown is capable of considerable modification and such modification as is within the scope of my claim, I consider within thespirit of my invention.

I claim :7

In pliers, the combination of a pair of crossed, pivotally connected, bifurcated arms, and jaw pivotally mounted in each bifurcation, each jaw having a transverse guide opening through it, and a rigid arm at one side thereof projecting into the guide opening in the other aw.

In testimony whereof, I afiix my signature hereto.

ANTON MAE.
